Features
Description
• High, stable efficiency over wide operating range
• Optimized for trailing- and leading-edge dimmer
• Precise PWM for primary PFC and dimming control
• Power cell for Vcc pre-charging with constant
current
• Built-in digital soft-start
• Foldback correction and cycle-by-cycle peak
current limitation
• VCC over/ under-voltage lockout
• Auto restart mode for short circuit protection
• Adjustable latch-off mode for output overvoltage
protection
The ICL8001G employs quasi-resonant operation
mode optimized for off-line LED lighting, especially
dimmable LED bulbs for incandescent lamp
replacement.
Precise PWM generation enables primary control for
phase cut dimming and high power factor PF>98%.
Significant improved driver efficiency, up to 90%,
compared to other conventional solutions. Tthe
product has a wide operation range (up to 26V) of IC
voltage supply and lower power consumption. Multiple
safety functions ensure a full system protection in
failure situations.
With its full feature set and simple application, the
ICL8001G represents an outstanding choice for quasi-
resonant flyback LED bulb designs combining feature
set and performance at minimum BOM cost.
